Simulation: remove particle nodes with outdated design

The design for how we approach the "Everything Nodes" project
has changed. We will focus on a different part of the project initially.

While future me will likely refer back to some of the code I remove here,
there is no point in keeping this code around in master currently.
It would just confuse other developers working on the project.

This does not remove the simulation modifier and data block. Those are
just cleaned up, so that the boilerplate code can be reused in the future.
